Various errors thrown in the Console when opening an HDRP project with a freshly built "Library" folder and project path up to 20 characters shorter than the longest allowed by Unity Hub

Steps to reproduce:
1. Create a new "3D (HDRP)" template project (Editor version 6000.3.0f1) with a project path up to 20 characters shorter than the longest allowed by Unity Hub
2. Open the created project and wait for it to load

Expected result: The project opens with no errors
Actual result: The project opens with multiple errors related to HDRP Shader Graph and VFX Graph

Reproducible with: 6000.0.62f1, 6000.2.13f1, 6000.3.0f1, 6000.4.0a5, 6000.5.0a1

Reproduced on: Windows 10, Windows 11 Pro (24H2 and 25H2)
Not reproduced on: No other environment tested

Notes:

• Most of the errors are related to Shader Graphs and VFX Graphs
• Different Unity versions throw errors with different Shader Graphs, for example: 6000.3.0b2 throws errors related to HDRP “Hair <…>.shadersubgraph” Shader Graphs and 6000.3.0a1 throws errors related to “WaterSurfaceGradients.shadersubgraph” and “AutodeskInteractiveTransparent.ShaderGraph”
• The errors no longer appear after clearing the Console or reopening the project but they reappear if the “Library” folder is rebuilt
• Different Unity Editor versions have different thresholds for project path length that reproduces this issue (with 6000.3.0f1, the project path length + name length in total can be up to 20 characters shorter than the longest allowed by Unity Hub to reproduce the issue)
